Description

Technical Field

[0001] The present invention relates to the technical field of double - headed threaded screws, and particularly to a disassembly tool for double - headed threaded screws. Background Art

[0002] As a key connecting part, the double - headed threaded screw is characterized in that threads are provided at both ends of the screw. After long - term operation, such screws are prone to difficult disassembly due to corrosion, deformation or excessive pre - tightening force.

[0003] Currently, the industry generally relies on general tools (such as adjustable wrenches, pipe wrenches, etc.) for disassembly operations. The surrounding working space is narrow, and it is difficult to use conventional tools; when disassembling, the screw is prone to rotate synchronously with the tool, and effective loosening cannot be achieved, which seriously affects the maintenance progress. Summary of the Invention

[0004] In view of the problems of narrow surrounding working space, difficulty in using conventional tools, and the screw being prone to rotate synchronously with the tool during disassembly, resulting in ineffective loosening and seriously affecting the maintenance progress, the present invention is proposed.

[0005] Therefore, the object of the present invention is to provide a disassembly tool for double - headed threaded screws.

[0006] To solve the above - mentioned technical problems, the present invention provides the following technical solution: A disassembly tool for double - headed threaded screws, comprising

[0007] A nut;

[0008] At least three brackets are installed on the outer surface of the lower nut, extending the range of the lower nut;

[0009] A moving member, installed on the bracket to provide a moving guide; and,

[0010] A pressing member, installed on the moving member and moving along with the movement of the moving member on the bracket. The pressing member includes an upper nut, and the moving distance of the upper nut is the height of the bracket;

[0011] The moving member drives the upper nut on the pressing member to move downward and press the lower nut, and then the lower nut is rotated to complete the disassembly of the double - headed threaded screw.

[0012] As a preferred scheme of the disassembly tool for double - headed threaded screws of the present invention, wherein: the bracket has a certain length and is equidistantly installed on the outer side of the lower nut. The length of the bracket determines the moving length of the upper nut, and the structure of the bracket is in the shape of the number "匚".

[0013] In a preferred embodiment of the double-ended threaded screw disassembly tool of the present invention, the bracket includes a movable surface, which is disposed on the inner side of the bracket, thereby forming a groove of a certain length and width on the inner side of the bracket.

[0014] In a preferred embodiment of the double-ended threaded screw disassembly tool of the present invention, the movable component includes a fixed cylinder mounted on a bracket. The fixed cylinder is a circular ring structure with a certain height. The fixed cylinder is positioned above the middle of the lower nut and serves as a guide for the movement of the entire movable component.

[0015] As a preferred embodiment of the double-ended threaded screw disassembly tool of the present invention, the movable component further includes a movable cylinder movably connected to the fixed cylinder. The movable cylinder has a certain length and a diameter smaller than that of the fixed cylinder. A pressing handle is installed on the movable cylinder to facilitate moving the movable cylinder up and down along the position of the fixed cylinder.

[0016] As a preferred embodiment of the double-ended threaded screw disassembly tool of the present invention, the pressing component further includes a limiting frame installed between the lower nut and the movable cylinder. The number of the limiting frames is the same as the number of the brackets. The limiting frame has a certain height to adapt to the height of the nut on the screw.

[0017] In a preferred embodiment of the double-ended threaded screw disassembly tool of the present invention, a rotating component is connected to the bracket, which is used to drive the lower nut to rotate, thereby assisting in the disassembly of the screw.

[0018] In a preferred embodiment of the double-ended threaded screw disassembly tool of the present invention, the rotating component includes a rotating ring on a movable surface connected to a bracket, and the rotation of the rotating ring drives the lower nut and the bracket to rotate synchronously.

[0019] In a preferred embodiment of the double-ended threaded screw disassembly tool of the present invention, the rotating ring is a circular ring structure, and the center of the rotating ring and the lower nut are the same. The diameter of the rotating ring is longer than the diameter of the upper nut, which facilitates the rotating ring to move through the upper nut.

[0020] As a preferred embodiment of the double-ended threaded screw disassembly tool of the present invention, the rotating ring is equipped with a rotating handle, the number of rotating handles is at least three, and the rotating handle is in the shape of the letter "L", with the upper part being inclined to facilitate pushing the rotating handle.

[0021] The advantages of this invention are as follows: The moving part drives the upper nut on the lower pressing part to move downward and squeeze the lower nut. The upper nut presses the lower nut to form a rigid connection. Then, rotating the lower nut allows the double-threaded screw to complete the disassembly work. The rotating ring passes through the upper nut to transmit torque, breaking through space limitations. The push handle provides a lever arm, and disassembly can be completed by a single person. This solves the problem that disassembly operations can only be performed with general tools (such as adjustable wrenches, pipe wrenches, etc.), the surrounding working space is narrow, and conventional tools are difficult to use. During disassembly, the screw is prone to rotate synchronously with the tool, which cannot achieve effective loosening and seriously affects the maintenance progress. Attached Figure Description

In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0032] Embodiment

[0033] Refer to Figure 1 - Figure 4 , for an embodiment of the present invention, a disassembly tool for a double-threaded screw rod is provided. According to the attached Figure 1 This device includes a lower nut 1; at least three brackets 2 are installed on the outer surface of the lower nut 1, and the brackets 2 are used to extend the range of the lower nut 1; a moving member 3 is installed on the brackets 2 to provide a moving guide; and a pressing member 4 is installed on the moving member 3 and moves along with the movement of the moving member 3 on the brackets 2. The pressing member 4 includes an upper nut 41, and the moving distance of the upper nut 41 is the height of the brackets 2; by driving the upper nut 41 on the pressing member 4 to move downward by the moving member 3 and pressing the lower nut 1, and then rotating the lower nut 1, the disassembly of the double-threaded screw rod is completed.

[0034] Among them, the brackets 2 have a certain length and are equidistantly installed on the outer side surface of the lower nut 1. The brackets 2 can be set to be snap-mounted on the lower nut 1 for easy disassembly or replacement. The length of the brackets 2 determines the moving length of the upper nut 41, and the structure of the brackets 2 is in the shape of the number "匚".

[0035] Among them, the brackets 2 include a moving surface 21, and the moving surface 21 is arranged on the inner side surface of each bracket 2, so that a groove surface with a certain length and width is formed on the inner side surface of the brackets 2.

[0036] Specifically, the moving member 3 includes a fixed cylinder 31 installed on the brackets 2. The fixed cylinder 31 is fixedly installed on the brackets 2. The fixed cylinder 31 is an annular structure with a certain height, and the fixed cylinder 31 is located at the middle position of the lower nut 1 and on the upper side. The fixed cylinder 31 is used as the moving guide for the entire moving member 3.

[0037] The movable component 3 also includes a movable cylinder 32 that is movably connected to the fixed cylinder 31. The movable cylinder 32 can rotate and move up and down. The movable cylinder 32 has a certain length and its diameter is smaller than that of the fixed cylinder 31. The pressing handle 33 installed on the movable cylinder 32 facilitates moving the movable cylinder 32 up and down along the position of the fixed cylinder 31.

[0038] Furthermore, the lower pressing component 4 also includes a limiting bracket 42 installed between the lower nut 1 and the moving cylinder 32. The limiting bracket 42, like the bracket 2, can also be set to be detachable to facilitate the overall operation and installation. The number of limiting brackets 42 is the same as the number of brackets 2. The limiting bracket 42 has a certain height to adapt to the height of the nut 41 on the screw.

[0039] The bracket 2 is connected to a rotating component 5, which can move up and down on the moving surface 21 of the bracket 2. The rotating component 5 is used to drive the lower nut 1 to rotate, thereby assisting in the disassembly of the screw.

[0040] Furthermore, the rotating component 5 includes a rotating ring 51 connected to the movable surface 21 on the bracket 2. The rotating ring 51 can only move up and down on the movable surface 21 on the bracket 2 and cannot rotate in a circle. The rotation of the rotating ring 51 drives the lower nut 1 and the bracket 2 to rotate synchronously. The up and down movement of the rotating ring 51 on the movable surface 21 is to adjust the rotation operation position to meet the appropriate operating space.

[0041] Among them, the rotating ring 51 is a circular ring structure, and the center of the rotating ring 51 and the lower nut 1 are the same. The diameter of the rotating ring 51 is longer than the diameter of the upper nut 41, which makes it easier for the rotating ring 51 to move through the upper nut 41.

[0042] Among them, a rotating handle 52 is fixedly installed on the rotating ring 51. There are at least three rotating handles 52, and the rotating handle 52 is in the shape of the letter "L". The upper part is inclined to facilitate pushing the rotating handle 52.

[0043] During operation, screw the lower nut 1 into the end of the double-ended threaded screw to be disassembled, ensuring that the lower nut 1 and the screw thread are fully engaged. The bracket 2, attached to the outside of the lower nut 1 via a snap-fit ​​mechanism, extends the operating range and avoids limitations in narrow spaces. The moving surface 21 on the inner side of the bracket 2 forms a guide groove, providing a movement path for subsequent structures. Pressing the handle 33 drives the moving cylinder 32 to move vertically downwards along the fixed cylinder 31, causing the upper nut 41 to move downwards. When the upper nut 41 presses against the lower nut 1, the two form a rigid whole through friction. The limiting bracket 42 located between the moving cylinder 32 and the lower nut 1 ensures that the upper nut 41 and the screw nut are height-matched. At this time, the rotating handle 52 on the rotating ring 51 can be pushed simultaneously, causing the rotating ring 51, the bracket 2, and the lower nut 1 to move together. With synchronous rotation, and by pressing the handle 33 on the other side to restrict the positions of the upper nut 41 and the lower nut 1, the double-ended threaded screw can be driven to rotate out in the opposite direction. The moving part 3 drives the upper nut 41 on the lower pressing part 4 to move downward and squeeze the lower nut 1. The upper nut 41 presses the lower nut 1 to form a rigid connection. Then, rotating the lower nut 1 completes the disassembly of the double-ended threaded screw. The rotating ring 51 passes through the upper nut 41 to transmit torque, breaking through space limitations. The push handle provides a lever arm, and disassembly can be completed by a single person. This solves the problem that disassembly operations can only be performed by general tools (such as adjustable wrenches, pipe wrenches, etc.), the surrounding working space is narrow, and conventional tools are difficult to use. During disassembly, the screw is easy to rotate synchronously with the tool, which cannot achieve effective loosening and seriously affects the maintenance progress.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
